Development and growth of some agricultural species on a subantarctic island.
In experiments at Melbourne (Australia, mean air temperature 10 deg C) and King Edward Point, South Georgia (British Antarctic Territory, mean air temperature 5 deg ) the species tested outdoors in pots were rape cv. Arlo, barley cv. Finlay, Lolium rigidum, pea cv. Alaska, rye cv. South Australian and subterranean clover cv. Dwalganup. Peas and barley (day-neutral) flowered 10 days later in South Georgia than in Melbourne. All species grew more slowly in South Georgia and all failed to set seed. Compared with growth at Melbourne, rye grew best in South Georgia and subterranean clover worst.
